The whole thing was spectacular - we were bivying on a small ledge, big enough just for 3 people and had this just in front of us.... simply amazing and one of the greatest moments I had in the mountains. Roman used 4MP Canon Powershot in automatic mode (I think).

Don't know how I missed this one till now?!?!?! Amazing sight; fascinating and scary at the same time, simply jaw dropping! Fantastic capture! Is it possible there was no storm from this spectacular cloud which looks like the edge of some crazy front that is approaching?!

Thanks - no storm from this one, next morning the sky was pretty much clear. I think the storms in the Sierras usually come from the west, from the ocean, this cloud was hanging on the east side of Sierras.
